The submersible mixed-flow column pump type ABS AFLX is designed for use where large volumes of process water or wastewater containing solid effluent must be pumped up to moderate heads. Equipped with a premium-efficiency IE3 motor, it is suitable for: • Hazardous locations

- Approval for ATEX (EX II 2G k Ex d IIB T4), FM and CSA available as an option

• Sewage in combination with screens• Return sludge or return activated sludge (RAS)• Combined sewage and surface water• Storm water protection• Industrial raw water and process water

Premium efficiencyThe AFLX pump benefits from significant efficiency in both motor and hydraulics, resulting in substantial savings: • Lower energy consumption • Reduced operating costs • Reduced maintenance costs • Less downtime caused by breakdowns and

blockages

Great savings means a healthier environment, reducing your carbon footprint and the risk of harmful overflows. The AFLX pump makes your operation more competi-tive while contributing to a greener future.

The right installation to fit any needsThe submersible AFLX pump can be installed accord-ing to the following, to fulfill virtually any customer requirements: • Steel column pipe installation • Concrete rising main installation

Main Applications

PE5

3

• Versatile range of mixed-flow impellers• Highly efficient three-to five-blade open-type mixed-

flow impellers• Low-vibration design• Low-NPSH design• Trouble-free pumping of liquids containing solids

in combination with screens (For detailed information please contact your local Sulzer representative)

• Applicable for delivering return sludge or return activated sludge (RAS) at wastewater treatment plants

• Adjustable inlet bellmouth with slotting• Significant energy savings throughout the pump

lifetime• Ability to restore pump efficiency after wear by

adjusting the inlet bellmouth• Efficient handling of fibrous material throughout

the hydraulic lifetime• Slotted casing wear ring adapted from the

Contrablock Plus series to ensure blockage-free operation

• Slim motor design• Opportunities for compact rising main and pumping

station design• Gearbox available from 132 kW for AFLX 1202

to 1207 - Wide range of gearbox ratios to meet the duty point with the best efficiency - Better adaptation compared to a direct high-pole motor drive - Higher efficiency and lower current due to the better power factor of 4-pole motors compared to high-pole motors - Lower weight

Hydraulic Features and Benefits

• Double mechanical seals• Silicon carbide/silicon carbide (SiC/SiC) for

maximum resistance against abrasives• Chemical resistance in wastewater and most other

industrial applications• Seal blockage prevention that reduces operational

costs

• Heavy-duty stainless steel shaft• Deflection at the mechanical seal minimized to

<0.05 mm / 0.002 inches• Increased safety against fatigue fractures• Extended seal and bearing life

• Heavy-duty bearings• Minimum lifetime of 100,000 h• Electrically insulated upper bearing as standard for

PE6, which protects against stray electrical currents and avoids micro-cratering in the raceway of the inner and outer rings

• Installation into rising main • Automatic self-centering of the pump and column

pipe by means of a conical coupling ring• No screw or bolt fixing needed

• Premium-efficiency IE3 motor in accordance with IEC 60034-30

Motor power and speed overview Motor features and benefits

• Class H (140°C / 284°F) insulation, temperature rise according to NEMA Class A up to 110 kW / 168 hp and Class B above

• Unprecedented motor reliability due to low winding and bearing temperature

• Extremely long motor lifetime

• Service factor 1.3• Short-term operation at lower voltage, higher

frequency (generator sets) and higher medium temperature

• Versatile cable types• Country-specific cables with European, FM or CSA

approval for use in sewage water

• Optional shielded cable (EMC)• For operation with frequency-controlled AC drives• Installation according to EMC directives

• Moisture DI probe in inspection chamber in standard execution

• Early indication of mechanical seal failure• Additional moisture DI probe (separate for cable

connection chamber and motor compartment) to provide early indication of moisture ingress, standard for PE6 and optional for PE4 and PE5

• Thermal protection switch in stator as standard• Motor protection in the event of a power supply

failure, e.g. low line voltage or single-phase operation• Additional separate thermal protection switch

(bimetallic, PTC or PT100) in the upper and lower bearing as an early warning of bearing malfunction, standard for PE6 and optional for PE4 and PE5

• Vibration sensor for indication of vibration and warning when the set limit is exceeded, optional for PE4 to PE6
